Of the 1.5 billion English speakers in the world, over half learned it as a second or additional language.

The “language of business”, English has become a foundational skill for anyone looking to work in an international business or at a leadership level, and many English as a Second Language (ESL) speakers find themselves working in English on a daily basis.

But working in your second or third language comes with a unique set of challenges and opportunities.

We spoke to five global leaders about the role English has played in their careers, the challenges of being an ESL speaker, and how businesses can create a culture where everyone has a voice.

A passport to leadership

Strong English skills open doors. More than three-quarters of people with advanced English skills are in senior or leadership roles, compared to just 32% of those with limited English proficiency.

ɫèAV Languages CTO, , describes English as a “passport for this new world of opportunities, opening many, many doors I wouldn’t have had access to.”

There’s a cumulative effect, with one door opening and leading to the next.

Brushing up on his English skills was the spark that won Perrucci a scholarship to Denmark. That semester blossomed into a six-year stay, multiple degrees, his first international job opportunity, and a career with well-known global brands.

Whether it was getting onto a top MBA program or that first role at a big international company, for all the leaders we spoke to, English has proved to be a career catalyst.

More diversity, more innovation, more revenue

For companies looking to innovate and stand out in a competitive global market, an international team is essential.

“We’re aiming to build models of childcare that don’t exist at the moment”, explains Founder and CEO, .

“To do that, we need diversity of thought. With an international team, it’s more likely that someone will say “hey, I was living in Cape Verde for a while, and I saw this interesting thing”.

It’s an approach that pays off. found that businesses with more diverse management teams are more innovative, leading to 19% higher revenues.

Global customers, global team

A more diverse team can also help businesses stay close to their customers.

As technology has made it easier to operate across multiple countries, businesses quickly find themselves responding to the different needs, preferences, and expectations of customers all over the world.

“Reflecting the global nature of our business in our workforce means we can build a better, more effective service and a more successful business as a result”, explains , CEO of .

To help them stay close to their 5.2 million members across 420 cities, Zeeck’s team at InterNations is made up of more than 50 different nationalities.

English is the main language both for the InterNations team and platform, helping them create “a sense of oneness and community by using a shared language”.

The ultimate brain training

The leaders we interviewed spoke, on average, four languages, with many working across multiple languages on a day-to-day basis.

That experience of jumping between different languages also develops important leadership skills.

“When you speak multiple languages,” explains Perrucci, “different parts of the brain have to work together and make connections… It teaches your brain to be flexible about what you see and the way you interpret it”.

Zeeck likened it to working out: “Just as going to the gym improves your physical wellbeing, the mental challenge of learning a new language is good exercise for the brain”. It’s one of the reasons he provides all of his team language training.

The mental load of language

But hopping between languages and navigating different cultural nuances can take its toll.

“People whose first language is English often overlook the computing power it takes to work in your second or third language,” explains, Managing Director of International Wellbeing,, who only spends around a third of his time speaking his mother tongue.

“Even when colleagues are fluent in the language you're communicating in, it might still take them a bit more energy than you expect”, he continues. “By Friday afternoon, for example, I’m struggling to think fluently in whichever language!”.

The challenge of speaking up

For those who are less confident in their English skills, it can significantly impact the way they contribute at work.

Less than half (48%)of ESL speakers feel comfortable speaking up at work, andonly 10%of employees with limited English proficiency felt they could express themselves fully at work.

The dynamic can change depending on who’s in the room. “I see the difference when ESL speakers are on calls with confident, fluent English speakers”, adds, CEO and Founder of.

“They speak less”, she continues, “they caveat their contributions with “I might be wrong”, and you can see their English actually worsens because they feel more stressed”.

Without the right culture and support, businesses miss out on the benefits of an international team they’ve recruited.

Conscious leadership

The task of building a team and helping overcome the challenges of global working falls to business leaders.

The five leaders we spoke to shared practical tips for supporting global teams, including acknowledging and proactively addressing differences, avoiding interrupting ESL speakers, and using voice notes for sensitive communication to allow tone and emotion to come through.

More fundamentally, ESL speakers need business leaders to build a culture where it’s ok to make mistakes.

Leaders with first-hand experience of being an ESL speaker are uniquely placed to understand their increasingly global teams, pre-empt their challenges, and nurture a culture that allows difference to shine.

The journey from local roles to global leadership positions hinges on strong communication skills. The stories shared by our leaders demonstrate how English proficiency not only unlocks individual career potential but also drives organizational success through innovation and diverse perspectives. By fostering a culture that values and supports language learning, businesses can harness these benefits, ensuring their teams are prepared to excel on the global stage.

    Teaching engaging exam classes for teenagers

    By Billie Jago
    Reading time: 4 minutes

    Teachers all over the world know just how challenging it can be to catch their students’ interest and keep them engaged - and it’s true whether you’re teaching online or in a real-world classroom.

    Students have different learning motivations; some may be working towards their exam because they want to, and some because they have to, and the repetitiveness of going over exam tasks can often lead to boredom and a lack of interest in the lesson.

    So, what can we do to increase students’ motivation and add variation to our classes to maintain interest?

    Engage students by adding differentiation to task types

    We first need to consider the four main skills and consider how to differentiate how we deliver exam tasks and how we have students complete them.

    Speaking - A communicative, freer practice activity to encourage peer feedback.

    Put students into pairs and assign them as A and B. Set up the classroom so pairs of chairs are facing each other - if you’re teaching online, put students in individual breakaway rooms.

    Hand out (or digitally distribute) the first part of a speaking exam, which is often about ‘getting to know you’. Have student A’s act as the examiner and B’s as the candidate.

    Set a visible timer according to the exam timings and have students work their way through the questions, simulating a real-life exam. Have ‘the examiners’ think of something their partner does well and something they think they could improve. You can even distribute the marking scheme and allow them to use this as a basis for their peer feedback. Once time is up, ask student B’s to move to the next ‘examiner’ for the next part of the speaking test. Continue this way, then ask students to switch roles.

    Note: If you teach online and your teaching platforms allow it, you can record the conversations and have students review their own performances. However, for privacy reasons, do not save these videos.

    Listening – A student-centered, online activity to practice listening for detail or summarising.

    Ask pairs of students to set up individual online conference call accounts on a platform like Teams or Zoom.

    Have pairs call each other without the video on and tell each other a story or a description of something that has happened for their partner to listen to. This could be a show they’ve watched, an album they’ve listened to, or a holiday they’ve been on, for example. Ask students to write a summary of what their partner has said, or get them to write specific information (numbers, or correctly spelt words) such as character or song names or stats, for example. Begin the next class by sharing what students heard. Students can also record the conversations without video for further review and reflection afterwards.

    Writing –A story-writing group activity to encourage peer learning.

    Give each student a piece of paper and have them draw a face at the top of the page. Ask them to give a name to the face, then write five adjectives about their appearance and five about their personality. You could also have them write five adjectives to describe where the story is set (place).

    Give the story’s opening sentence to the class, e.g. It was a cold, dark night and… then ask students to write their character’s name + was, and then have them finish the sentence. Pass the stories around the class so that each student can add a sentence each time, using the vocabulary at the top of the page to help them.

    Reading –A timed, keyword-based activity to help students with gist.

    Distribute a copy of a text to students. Ask them to scan the text to find specific words that you give them, related to the topic. For example, if the text is about the world of work, ask students to find as many jobs or workplace words as they can in the set amount of time. Have students raise their hands or stand up when they have their answers, award points, and have a whole class discussion on where the words are and how they relate to the comprehension questions or the understanding of the text as a whole.

    All 4 skills –A dynamic activity to get students moving.

    Set up a circuit-style activity with different ‘stations’ around the classroom, for example:

    • Listening
    • Reading
    • Writing (1 paragraph)
    • Use of English (or grammar/vocabulary).

    Set a timer for students to attempt one part from this exam paper, then have them move round to the next station. This activity can be used to introduce students to certain exam tasks, or a way to challenge students once they’ve built their confidence in certain areas.

    Did you know that improving your English proficiency can increase earning potential by up to 50% and safeguard your career against AI? Recent research by ɫèAV highlights that English is not just a skill but a career-defining advantage in today’s globalized workplace. For millions of adult learners, the journey from the classroom to the workplace requires more than general conversational abilities—it’s about gaining targeted, job-ready skills as quickly as possible. For English language educators, understanding what “jDz-𲹻” English is and how to identify “jDz-𲹻” skills can provide a significant advantage in ensuring learners are prepared to communicate effectively and collaborate with their future coworkers.

    That’s where the Global Scale of English (GSE) Job Profiles comes in. For educators and program developers, it offers a bridge between real-world job skills and the English learners need to perform them. Whether you’re creating programs for nursing assistants, hospitality workers, or IT professionals, this tool ensures that learners build the precise English skills they need to thrive in their roles.

    Let’s walk through how to create a GSE Job Profile and explore its practical use for building programs that align with today’s professional realities.

    Teacher technology adoption: What’s age got to do with it?

    By Jennifer Williams
    Reading time: 4 minutes

    Educators, by design, are innovators. Living and working in a constant state of beta, teachers bring to the classroom a natural desire to explore and better understand new practices and methodologies to support students in their search for knowledge.

    Guided by an internal drive to make the world a better place and powered by the rewards of working daily with the youth that can create that positive change, teachers collectively are part of a profession different from any other. Within one classroom on any single day, a teacher can become a scientist, a historian, an inventor, or a scholar. Over time, whether in a one-room schoolhouse a century ago or in a technology enhanced classroom of the digital age, these defining characteristics of “teacher” have seemed to stay constant.

    Bridging the generational and digital divide

    Today, as citizens of our digital and global world, we are in an extraordinary time where divides are closing and collaboration becomes standard – where differences are truly celebrated and associations are surpassing separations in society.As educators, this change reflects what we have consistently asserted in our classrooms.

    Yet, terms like 'generational gap” and “digital divide” suggest a significant separation between us as teachers and our students. In truth, teachers and students are increasingly using asharedlanguage of innovation and exploration. Rather than sticking to notions of a technology-based generational divide, many are transcending the labels of “digital immigrants” and “digital natives”.

    This is further reinforced by current research demonstrating that technology adoption in education has less to do with age and instead is based more on exposure and experience (Bennett & Maton, 2010; Bullen, Morgan, & Qayyum, 2011; Guo, Dobson, & Petrina, 2008; Helsper & Eynon, 2010). As opposed to a focus on divides, this new evidence offers supportive pathways of possibilities to bring together older and younger generations in the process of learning in our world through exploration and wonder.

    Embracing skill development

    Moving attention away from a fixed age factor to emphasizing a continuum of proficiency based on exposure and experience enables teachers of all ages to identify as part of this digital age of education. Though digital technologies are fixtures in the daily lives of many (if not most) of our students, the ways students use technologies are not always consistent.

    Students of today – like students of previous generations – continue to need the guidance of teachers in finding ways to take and apply their understanding of technology to effectively convey perspectives with the world, influence the opinions of others, and contextualize and synthesize information in meaningful ways.

    Timeless lessons from teachers

    Teachers as innovators – young and old, tech-savvy and tech-novice – have extraordinary gifts to bring to their students, who are also navigating through digital environments. Though there are countless lessons teachers bring to students, here are several timeless ones that transcend any generation of teaching. Teachers guide students to use advanced technologies so that they can be...

    Critical consumers

    Today, students in our classrooms are bombarded with information at nearly every moment in time. With basic searches for information often leading students in multiple directions, research at every level has now become a highly complex and sophisticated process. The result is that we now see learning practices shifting from finding answers to discovering more questions.

    Teachers can guide students to evaluate and consume information critically. By promoting transparency and sharing, they help learners consider context and sources, reason with evidence and build knowledge.

    Creators of rich content

    As classrooms advance as blended learning environments, seamless integration of technologies and innovative teaching practices offers students opportunities to transform from passive learners to active content creators. With countless digital tools available for content creation, students can seek guidance from teachers on matching the best tool to a particular communicative purpose.

    Teachers who are skillful in creating synthesized messages can show students ways to comprehend and compose with combinations of digital technologies. Less in the role of directing lessons, the teacher becomes a catalyst for learning, inspiring students to work creatively and collaboratively to solve problems and respond to instructional lessons as producers of information.

    Centered on relationships

    A defining quality of a master teacher is the ability to create a positive learning community built on empathy and understanding. The focus on relationships in these classrooms models the continued importance of valuing alliances and friendships.

    Soft skills, such as joy, honesty, trust and respect, become even more essential as our students continue to interact in a highly networked and diverse world. Balance, too, becomes a critical area for discussion as students look to divide attention, time and social-emotional reserves between onscreen and in-person experiences.

    Within responsive classrooms and digital learning spaces that keep emphasis on the formation of relationships, teachers can offer opportunities for students to develop through collaboration, teamwork, solidarity and conflict resolution.

    Resilient in endeavors

    Our students are looking out onto a world where anything is possible. Digital age technologies are empowering students to believe: “if you can dream it, you can do it”. The impossible is within reach, and a mindset of grit and determination moves sparked ideas to a place of accomplishment and excellence.

    Through the creation of learner-driven classrooms centered on the student, teachers can help guide students to narrow their interests and ultimately find their passions. With relevance and authentic purpose, teachers can connect students in the process of learning through design thinking and trial and error – shifting the outlook from fear of failure to resilience and 'stick-to-itiveness' to advance learning to a place of discovery and invention.

    And it is this mindset – a position of inquiry and exploration – held by students and teachers, young and old, that can show that great will come from risk. We all just need to be ready to try.
